Alachua County Sheriff’s Office(PITTSBURGH) -- The Pittsburgh Steelers waived rookie running back Chris Rainey on Thursday, following his arrest on one count of simple battery in Florida.

The 24-year-old Rainey was taken into custody by police in Gainesville after he was allegedly involved in a physical altercation with his girlfriend. Police says Rainey and his girlfriend were arguing over his cellphone. Rainey’s girlfriend entered a vehicle, at which time, police say, Rainey attempted to pull her out.

Witnesses told police they observed Rainey slapping his girlfriend across the face with an open hand. She managed to pull away, but Rainey chased after her.

“Chris Rainey’s actions this morning were extremely disappointing,” Steelers General Manager Kevin Colbert said. “Under the circumstances and due to this conduct, Chris will no longer be a member of the Pittsburgh Steelers.”

In his rookie campaign in 2012, Rainey rushed for 102 yards and a pair of touchdowns on 26 carries.
